Fast-growing Astraseal has extensively expanded its offering of high-performance composite doors made in-house with the market-leading Distinction Doors slab.

Boasting a stunning woodgrain finish based on real oak, and coming available in an extensive range of over 30 styles and 40 colours, the Distinction slab is the most authentic and aesthetically versatile on the market.

Thanks to its rigid polymer sub-frame and high-density, high-impact resistant GRP skin, warping is a thing of the past. What’s more, it offers exceptional security, and a track record of achieving PAS24:2016 and Secured by Design accreditation.

A Distinction slab is also more than 17% more thermally efficient than solid and timber panelled alternatives, and comes with a 25-year warranty.

Astraseal also incorporates the Distinction slab in its extensive range of 30-minute and 60-minute fire doors.

The firm’s FD30 is made with the Winkhaus Ecoframe outerframe, while the FD60 is made with a bespoke timber outerframe. Both doors are available in a range of colours and styles.
